Abstract
A significant reduction in distillation tower
energy requirements can be achieved by mechanical
vapor recompression. Three design approaches for
heating a distillation tower reboiler by mechanical
vapor recompression are presented. The advantages
of using a screw compressor are discussed in detail.
An example of a xylene extraction tower is sited,
illustrating the economic attractiveness in which
a simple payback period of less than two years is
achievable.
